Does anyone know what the three electrical connectors to the Transmission are? Neutral switch and Clutch position make sense. There is a third open plug on the top firewall side it has a black plastic molded tower shape. No Idea if it needs to be plugged into something. Did a clutch replacement and power comes on but starter will not crake and there is no Solenoid noise. I just posted an E-Bay photo that shows the tower connector in question.
